Ethnographic Knowledge in Urban Planning–Bridging the Gap between the Theories of Knowledge-Based and Communicative Planning

‘Knowledge-based’ approaches have recently made a breakthrough in urban planning. How to develop balance in knowledge-based planning between abstract and scientific knowledge, on the one hand, and ‘local knowledge’ on the other hand has been long debated. To this debate, we add a form of knowledge with potential for sustainable urban planning, i.e. ethnographic knowledge that could transmit an understanding of urban dwellers’ daily practices and values to planning organisations. Theoretical literature is the foundation of our argument, which we illustrate with a case study involving urban planners and decision-makers in the Helsinki region of Finland.
